[0002] In the stable operation of the power system, the substation plays a crucial role. As the core hub for power conversion and distribution, it has numerous internal devices and a complex operating environment. Ensuring the safe and reliable operation of the substation is of vital importance. The operation and maintenance work is a key link to ensure the normal operation of the substation, and the camera equipment plays an indispensable role in it, providing key information such as the operating status of on-site equipment and the environmental conditions for operation and maintenance personnel.

[0003] Traditional substation camera equipment often acts independently and lacks an effective unified management system. When operation and maintenance personnel face a large amount of monitoring information, it is difficult to quickly screen out key content. When querying the operating conditions of a certain substation equipment, operation and maintenance personnel need to switch and search among different monitoring systems and equipment, consuming a large amount of time and energy, which seriously affects work efficiency. Moreover, due to the lack of a unified display platform, it is difficult for operation and maintenance personnel to intuitively understand the observation areas of each camera equipment and their associations. In the face of emergencies, they cannot quickly make accurate judgments and decisions.

Moreover, throughout the drawings, the same reference numerals are used to represent the same components. In the drawings:

[0045] Figure 3 A schematic structural diagram of equipment for equipment monitoring of a digital substation provided by an embodiment of the present application. Specific implementation manners

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0047] The solution of the present application can be implemented based on a terminal with data processing capabilities, and the terminal can be a computer, the cloud, a server, etc.

[0048] Next, in combination with Figure 1 As described above, the equipment monitoring method of the digital substation of the present application may include the following steps:

[0049] Step S110: Obtain the position information of each camera device in the substation, and obtain the shooting area of each camera device.

[0050] Specifically, before three-dimensional modeling of the substation, various equipment in the substation needs to be collected. Specifically, a three-dimensional laser scanner can be used for scanning to obtain the position information of the camera device. Further, after determining the shape of the camera device, the shooting direction and angle range of the camera device can be determined, so as to obtain the shooting area of the camera device.

[0051] Step S120: For each camera device, determine each substation device within the shooting area of the camera device, and associate each substation device with the camera device as the device association information of the camera device.

[0052] It can be understood that there may be one or more substation devices within the shooting area of the camera device, indicating that the camera device can monitor these substation devices. Therefore, these substation devices can be associated with the camera device, so that when it is necessary to query the operating conditions of a certain substation device or the shooting content of a certain camera device, it can be quickly retrieved, improving the information management efficiency.

[0053] Step S130: Perform three-dimensional modeling of the substation according to the position information of each camera device and the device association information of each camera device to obtain a digital substation model.

[0054] Among them, the digital substation model can include all substation equipment models within the substation, all substation building models, the connection relationships between substation equipment models, the positional relationships between substation equipment models and substation building models, all camera devices, and the substation equipment corresponding to the actual situation within the shooting areas of all camera devices.

[0055] It can be understood that through three-dimensional modeling of the substation, the actual situation of the substation can be reflected more realistically and accurately. The digital substation model not only includes the spatial positions of the equipment, but also incorporates the corresponding relationships between the monitoring devices and the monitored devices, providing a more reliable virtual environment for subsequent monitoring and operation and maintenance.

[0056] Step S140: In response to an instruction to monitor a first target substation equipment, determine all first target camera devices associated with the first target substation equipment in the digital substation model.

[0057] Specifically, the user can select the first target substation equipment to be monitored on the digital substation model. For example, by clicking on the substation equipment, the respective camera devices associated with the substation equipment can be queried.

[0058] Step S150: Retrieve several first target camera devices from all the first target camera devices in the digital substation model and display the shooting area images of the several first target camera devices.

[0059] Specifically, different camera devices associated with the first target substation equipment can monitor the substation equipment from different shooting angles. Therefore, multiple monitoring perspectives can be provided to more intuitively and clearly display the real-time working conditions of the substation equipment.

[0060] Furthermore, considering providing a better visual experience for the user, not all of them need to be displayed at once. Several shooting area images of the first target camera devices can be automatically selected for display. The criteria for selecting the several first target camera devices for display can be that when these first target camera devices monitor the first target substation equipment, more effective information of the substation equipment can be obtained. In this way, the user can intuitively and clearly observe the real-time working conditions of the substation equipment without causing visual confusion to the user.

[0061] It can be understood that when a command to monitor the first target substation equipment is received, all the first target camera devices associated therewith can be quickly determined in the digital substation model, and several of them can be retrieved for display. This enables the operation and maintenance personnel to obtain the monitoring images of the target equipment in the first time, without blindly searching among numerous monitoring devices, greatly shortening the monitoring response time. Especially when dealing with emergencies, it can provide strong support for quick decision-making.

[0062] The equipment monitoring method of the digital substation provided in this embodiment includes: obtaining the position information of each camera device in the substation, obtaining the shooting area of each camera device, for each camera device, determining each substation equipment within the shooting area of the camera device, and associating each substation equipment with the camera device as the equipment association information of the camera device. According to the position information of each camera device and the equipment association information of each camera device, three-dimensional modeling of the substation is performed to obtain a digital substation model. In response to a command to monitor the first target substation equipment, in the digital substation model, all the first target camera devices associated with the first target substation equipment are determined, several first target camera devices are retrieved from the digital substation model, and the shooting area images of the several first target camera devices are displayed. Thus, by associating the camera devices with the substation equipment, a comprehensive and systematic information network is constructed, enabling the operation and maintenance personnel to quickly query the operating conditions of the target substation equipment, efficiently monitor the substation equipment, improve the information management efficiency, and ensure the safe and stable operation of the substation.

[0063] Considering that when there is abnormal operation of equipment in the substation, it is necessary to quickly locate the abnormal equipment to assist the operation and maintenance personnel to quickly master the scene. Based on this, the equipment monitoring method of the digital substation proposed in this application may further include:

[0064] S1. When the second target substation equipment in the substation has an abnormality, in the digital substation model, all the second target camera devices associated with the second target substation equipment are determined.

[0065] It can be understood that the digital substation model can obtain and update the status of the substation equipment in real time. Therefore, when there is abnormal operation of substation equipment in the substation, the digital substation model can obtain it in real time and then find the associated camera devices.

[0066] S2. Retrieve several second target camera devices from all the second target camera devices in the digital substation model, and display the shooting area images of the several second target camera devices.

[0067] It can be understood that different camera devices associated with the second target substation equipment can capture and monitor the substation equipment from different shooting angles, so multiple monitoring perspectives can be provided to more intuitively and clearly display the real-time working conditions of the substation equipment.

[0068] Furthermore, considering providing a better visual experience for users, it is not necessary to display all at once. Instead, several captured area images of the second target camera devices can be automatically selected for display. The criterion for selecting the several second target camera devices for display can be that when these second target camera devices capture and monitor the second target substation equipment, they can obtain more effective information of the substation equipment. In this way, users can intuitively and clearly observe the real-time working conditions of the substation equipment without causing visual confusion to the users.

[0069] In some embodiments of the present application, the process of retrieving several first target camera devices from all the first target camera devices mentioned in the foregoing embodiments from the digital substation model is introduced, which may specifically include the following two situations:

[0070] First, if the number of control boxes for displaying camera device images has been preset, then retrieve from the digital substation model the first target camera devices with the same number as the control boxes among all the first target camera devices.

[0071] It can be understood that the user can preset the number of control boxes for the images to be displayed, and the number of control boxes corresponds to the number of camera devices. For example, the user can pre-select 5 image display control boxes. When the digital substation model retrieves from all the first target camera devices, 5 first target camera devices that contain the most information about the first target substation equipment can be screened out for display.

[0072] It should be noted that if the number of first target camera devices associated with the first target substation equipment is less than the preset number of control boxes, then the monitoring images of all the first target camera devices can be displayed.

[0073] Second, if the number of control boxes for displaying camera device images has not been preset, then retrieve 4 first target camera devices from all the first target camera devices in the digital substation model.

[0074] It can be understood that when the number of control boxes is not specified, the default number for display can be 4, so that the monitoring images of the first target substation equipment are displayed in a four-grid format for a better viewing experience for the user.

[0075] Considering that the images of several camera devices for automatic screening of digital substation models are not the perspectives that users need to view, a function of switching the images can be provided to users. In some embodiments of the present application, after displaying the images of the shooting areas of the several first target camera devices mentioned in the foregoing embodiments, in response to an instruction to switch the shooting area images, the images of the shooting areas of the currently displayed first target camera devices can be partially or fully switched to the images of the shooting areas of other first target camera devices.

[0076] Specifically, the user can select one or more monitoring images to be switched, click the switch, and select the images of the shooting areas of other first target camera devices to be replaced. By operating in this way, the user can freely select the perspectives that need to be viewed, improving the user experience.
